Toall whom it may concern.

Be it known that we, FRANK HoL'r MER- .osn, mechanical -engineer,- and -HEnaEn'r FREDERICK I'IASSALL BLEAsE, mechanical, en- I gineer, both subjects of the King of Great Britain and Ireland, and residents of Melksham, Wilts, England, have invented certainnew and. useful Improvements inor Relating to Machines for the Mannfacture of Tire-Covers, of which the following is a specification.

This invention relates to the manufacture of tire covers, composed 'of fabric coated with rubber, 'havingja regular or irregular portion which fits the wheel rim. The object of this invention is to provide a machine for shaping that regular or' irregular. portion which fits the wheel rim.

A machine made in accordance with'this' invention. comprises a rocking =n1emher adapted to be rocked about the center on which the core is mounted, carriers on said rocking member,- arms on said carriers disposed on each side'of. the core, means for moving the carriers simultaneously toward or away from the. centerof the core, spring pressed plungers on' said'arms containing rollers, and adapted to bear on the core or fabric, at'or near that portion which fitsthe wheel rim, means for moving the arms -on one or both sides of the coreaway from the" core and means for oscillating the rocking member.

Means are provided for .positioning the beads or the cores for any regular or irregu- .lar portion'which fits the wheel rim'in correct position on the fabric," prior to their being covered with the outer layer or layers of 'fabric forming. the cover.

Referring to the accompanying drawin s:-'-

Fig: 3 is a sectional plan;

Fig. 4 is a sectional side elevation;

Fig. 5 is a front elevation; and

Fig.- 6 is a plan.

On the frame a of the machine is mounted a main shaft 6 adapted to he drivenby the pulley c. On the'shaf-t b are mountedtoothed speed gear wheels d e f adapted to mesh with ar wheels 9 h j on the countershaft k. n the shaft 1) is apinion m,

disks p p which form the subject matter of a concurrent patent application. The pin 'ion m drives also the spur wheel 9 on the shaft 7*. On the shaft 1' is a wheel a (not shown in plan) which drives the spur wheel t.

The rocking member 2 is mounted on a sleeve 16 on a shaft '3 on the frame a'of the machine. iOn-the spur wheel at is. a studv a (see Figs. 4 and 5) which engages with a radial slot w in the. boss w" on the rocking member 2. On rotatin the wheel t thestud 4') travels in a circuir path w shown in'dotted lines in Fig. 5, thus causing a rocking motion of the ing member is posed guides 4.

member 1'. The rock-- provided with radially disshaft is adapted to engage with a threaded 7 lug or nut 6 on a carrier 7. Each carrier is provided with a fixed arm 8 and an arm 9 pivoted at 10. The pivoted arm 9 is held 1n positionbya sprin 11 .throu h a lun er. .12 and lever 13 g g p g carrying rollers 15, 15, which are adapted to bear .on that portion. of the work' which forms the be'ad'ofsthev tire being formed by the machine. These rollersare preferably placed in steps. .so as to press the material into. the desired form "working gradually around the tire asv the core rotates, the

the shaft 3' is disposed a. sleeve 16 which carries a beveledwheel 17 which is adapted squared endof theshaft 18. On'each shaft 5 is 'a' beveled pinion 21 which engages wheel 17; The position of v.rollers tending to cause the fabric to draw fromthe crown toward and over the bead.

- to be rotated througha worm 19 and worm a wheel '20 by .av handle adapted to fit the the carriers is indicated by means of a .pointer 22 .which passes over a scale 23 as they are moved to or from the center of the shaft 3. Onthe shaft 3 is disposed the core 24 on which the tire is be molded. On the shaft'k is a beveled pinion 25 (Fig. 3) adapted to drive the shaft; 3 on which the core is mounted through worm 29 and worm action.

The means for fixing the bead or thecore for any regular or irregular portion which fits the wheel rim in correct'position on the fabric prior to their being covered with another layer or layers of fabric comprise a carriage 26 on a slide 26 mounted on the frame of the machine and carrying springpressed plungers 27 disposed on each side of the core and carrying rollers 28'at right angles to the plane of the core or otherwise suitably. The said rollers which] are referred. to hereafter as positioning rollers are mounted in said plungers 2'1. The carriage 26 on the slide 26 can away from the center of the core by means of a screwed shaft 31 engaging a screwed lu or nut 31 fixed on the carriage 26*.

n operation the layers of fabric forming the foundation of the tire are placed on the core and shaped. After the necessary plies of canvas have been put on, the beads or cores of any regular or rregular portlon.

which are adapted to fit the wheel rim are placed on the canvas and their position accurately adjusted by means of the'positiom ing rollers. After the beads or above mentioned cores are in position, the said positionand the remaining plies of canvas are placed in position so as'to cover the beads or above mentioned cores.' The rocking member is then placed in position so that the rollers press against the fabric and set in motion to mold the bemoved toward orcarriers on said rocking member;

mounted on sa d carrler, means for pressing scribing witnesses.

canvas on to the beads to the desired form" as the core on which the fabric is disposed is rotated so as to bring diflerent parts of the tire successively under the action of the rollers.

\Nith a machine made in accordance with this invention the whole of thesurface of v the head or that part of the regular or 1rre'-' gular portion which fits the wheel rim is pressed by the rollers disposed one in advance of the other whereby the bead is effectively shaped, thus obviating any air holes or puckers in the material. a

What we. claim and desire to secure by Letters Patent is A machine for shaping on a core dis osed on a shaft, tire covers, composed of abric coated with rubber provided. with beads or projections adapted to fit the rim of awheel,

said machine comprising a rocking member,-

rollers said rollers against the fabric, means forescillating' said rocking member ter of the shaft on which the core is mount ed, and means for moving said carriers in- .dividually and collectively-toward and away from the center of said core.
